Hi folks, I am trying to teach myself how to run a milling machine and I have a speed chart out of a Bridgeport manual on my tool box.It apears to be for hss tooling, for example, low carbon steel-90 sfpm. If I go to carbide end mills, which I'm seriously considering, is there a multiplier for this table? I think I downloaded the manual from this site it was for a 1966 mill.
I burned out a 1/4 " hss end mill pretty quickly today using this table but it was used slightly before a friend gave it to me. I had pretty good results though with a 1/2" end mill.
Another question I'd like to ask is, do you use misters on your mills? Where do you buy them and do they save you much money in tooling?
Thanks for any help on these matters and I'm sure there will be more to follow.
